It's Meter Reading Week

The unit rate domestic customers are paying for their energy goes down on October 1st. So if you submit meter readings to your energy supplier (which is anyone without a smart meter who pays by Direct Debit, or on receipt of bill, or your smart meter isn't working), try to take a reading within a few days either side of the rate change - which is Sunday 1st October - in just a couple of days! (if you end up taking the reading after Sunday, most suppliers let you backdate a few days) - this will reduce the risk of your supplier estimating you've used more at the higher rate than you actually have. If you're not confident reading your meter - check out this guide which covers all different types of meters, including smart ones:
